Meghan Markle, 36, and Prince Harry, 33, were in Birmingham for International Women’s Day yesterday.

The visit was widely photographed, and Meghan and Harry were seen greeting crowds – with Meghan even hugging one little girl.

The former Suits actress was impeccably dressed in a navy and cream J. Crew coat.

But one thing many may not have noticed was Meghan’s wardrobe malfunction – did you spot it?

The navy blanket coat was belted at the waist, and looked fantastic from the front.

From the back, however, it was a different story – and Meghan’s stylist may need to go back to fashion school.

A temporary stitch, which should be removed, was left visibly holding together her coat vent.

The white thread of the stitch could be seen agains the dark navy of the coat.

The error did not stop Meghan from looking her best, and she stunned in the coat which she paired with a white polo neck jumper from All Saints and plain black three-quarter length Alexander Wang trousers.

Prince Harry’s fiancee completed the look with a small navy handbag and black suede court shoes.

But the look did break what is considered a key style rule – that blue and black should never be worn together.

Meghan’s stylish outfit made a strong case for breaking the fashion edict.

The former Suits actress wore her hair, which was looking very long, curled over her shoulders.

Keeping her makeup simple, Meghan wore smoky etes and a nude lip. Her nails were also bare – as is the custom for royal women.

Meghan has been following royal style rules relatively closely since her engagement to Prince Harry.

One thing she has picked up in particular is “the Duchess slant”. This is a seating position named after Kate Middleton, but it has been in the Royal Family for much longer and has been used by the Queen and Princess Diana.
